摘要： A communication technique enables the efficient transmission of data through a communication link having a large delay bandwidth product and/or a high bit error rate. The communication technique multiplexes data from one or more data sources through a plurality of communication connections to increase the overall throughput and to reduce the average data transfer delay of the communication link. Each communication connection has a set of communication connection parameters that may be uniquely configured so that each connection carries a particular type of data at a particular effective priority level. Each communication connection may be uniquely configured to have a particular sending buffer size, to deliver messages having a particular length to an underlying layer and to send the messages into the link at a particular rate to orchestrate the manner in which the communication connections send data through the link.

摘要： An asset tracking system for use in a process control environment may include one or more asset tracking devices and an asset tracking host. The asset tracking device may receive signals corresponding to a position or location of an asset to be tracked, and may communicate, using an industrial automation protocol such as wireless HART, an indication of the position to the asset tracking host. The signals may be GPS signals that are re-radiated into the process control environment. Other information, such as environmental data, may be communicated in conjunction with the position of the asset. The asset tracking host may store and/or display the data or information included in the message, and may send a different message to the asset tracking device. An asset tracking device may be included in a field device, a network device, or a portable communications device used in the process control environment.

摘要： A web services-based communication system and technique uses an information server to facilitate the communication of process control data and analysis results between a plurality of web services coupled to a communication network. A graphical user interface coupled to the network enables users to store user profile information and configuration information in a database within the information server. The information server uses the configuration information and the profile information to control the operations of a scheduler and a router within the information server to enable users to selectively view process control information via the graphical user interface and to route process control information to appropriate ones of the web services.

摘要： Systems and methods of transmitting process control information to a portable communication device associate a resource link with the process control information and transmit the process control information and the resource link to the portable communication device. A session identifier is associated with the process control information and the session identifier and the resource link are transmitted to the portable communication device. A message and the resource link associated with the process control information are provided at the portable communication device. A user selects the resource link to initiate a communication link between the portable communication device and a wireless communication service. The portable communication device may receive one of video information, audio information, still image information, and software application information in response to initiation of the communication link between the wireless communication service and the portable communication device.

摘要： Methods and systems for integrating external and/or enterprise data into a process control system are disclosed. A user interface may be provided to enable browsing and selection of a data item from an external and/or enterprise data source. The selected data item may be associated with a process control entity. At run time, independent of a configuration of the process control entity, an external data integration server or instance of an external data integration service at a process control computing device may periodically communicate with the data source to obtain an updated current value and updated current status for the selected data item for use by the process control entity. The external data integration server and/or external data integration service may consolidate access of external/enterprise data across process control entities, optimize communications with various data sources, and maintain a status of communication with each various data source.

摘要： A portable computer for use in interfacing to a process control system having a host system includes a housing adapted for hand-held operation, a processing unit disposed within the housing and a computer readable memory disposed within the housing and coupled to the processing unit. The portable computer also includes a display, a keypad and a radio frequency transceiver adapted to communicate with the host system, all of which are disposed within the housing and communicatively coupled to the processing unit. A first software routine stored in the computer readable memory processes a user input received from the keypad and sends a command to the host system via the radio frequency transceiver. Additionally, a second software routine stored in the computer readable memory receives process information sent from the host system in response to the command and displays the received process information via the portable computer display.

摘要： A transactional data communications system and method communicates information within an enterprise having a process control system and a plurality of information technology systems that are communicatively coupled to the process control system via a web services interface and a transactional information server. The system and method generates transactional process control information and formats the transactional process control information based on an extensible markup language input schema to form formatted transactional process control information. The system and method sends the formatted transactional process control information to the transactional information server via the web services interface and maps the formatted transactional process control information to an extensible markup language output schema associated with one of the plurality of information technology systems to form mapped transactional process control information. The system and method then sends the mapped transactional process control information to the one of the plurality of information technology systems.

摘要： An I/O-abstracted configuration is defined for a field device that has not yet been assigned or allocated to communicate via a particular I/O device or I/O network within a plant, and this configuration is stored in a device placeholder object in a back-end environment of the plant. Thereafter other objects, modules, applications, user interfaces, etc., that are to execute in the back-end environment of the plant to communicate with the field device during on-line operation of the plant may be designed, built, configured, and tested using the device placeholder object without any actual communications with the field device and without assigning the device placeholder object to a particular I/O channel or I/O network. A commissioning system which may create and store one or more device placeholder objects in a database within the back-end environment of the plant includes an execution engine that executes one or more other back-end environment objects to be commissioned and tested, and a communication interface that determines, from the device placeholder object if a field device is in an I/O-unallocated device state. If so, the communication interface uses the configuration data stored in the device placeholder object to verify that the form, format, and configuration of the object being tested is correct to properly communicate with the field device. Moreover, a simulation engine can generate simulated device signals to enable further testing of the object.
